CORK-CUTTING MACHINE.

To all whom it may concern.

Be it known that I, ANTON GOLD, a citizen of the United States, residingat Newark, in the county of Essex and State of New Jersey, have inventedcertain new and useful Improvements in Cork-Cutting Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appert-ains to make and use the same, reference being had to theaccompanying drawings, and to charactors of reference marked thereon,which form a part of his specification.

The present invention has reference, generally, to improvements incorkcutting machinery; and, this invention relates, moreparticularly,t-o novel construct-ion of powerdriven cork-cutting machinewhich is of a simple construction, and is highly efficient in character.

This invention has for its principal object to provide a novelconstruction of power driven cork-cutting machine which is automatic inits operation.

A further object of this invention is to provide a novel automaticcork-feeding mechanism operating in conjunction with the cork-cuttingdevices, whereby the corkbark, from which the corks are to be cut, isautomatically fed to the said cork-cutting devices of the machine, saidcork-feeding mechanism comprising a set of feeding rolls and a timedstop-mechanism which retains the cork-bark in front of thecutting-devices during the cutting operation.

Other objects of the present invention not at this time moreparticularly enumerated, will be clearly evident from the followingdetailed description of the same.

l Vith the various objects of the present invention in view, the saidinvention consists, primarily, in the novel cork-cutting machinehereinafter more fully set forth; and, the said invention consists,further more, in the novel arrangements and combinations of the variousdevices and parts, as well as in the details of the construction of thesame, all of which will be hereinafter more fully described, and thenfinally embodied in the clauses of the claim which a re appended to thisspecification, and which form an essential part of the same.

construction of cork-cutting machine made according to and embodying theprinciples of my present invention; and Fig. 2 is a plan or top view ofthe same. Fig. 3 is a detail transverse section taken on line 33 in saidFig. 2, looking in the direction of the arrow 00, the said view beingdrawn on an enlarged scale; and Fig. 4 is a detail 1011- gitudinalsection, taken on line 4 4E in said Fig. 2, looking in the direction ofthe arrow 7 this view being also drawn on an enlarged scale. Fig. 5 is adetail horizontalsection, taken on line 55 in said Fig. 1, lookingdownwardly, said view being made on an enlarged scale; and Fig. 6 is asimilar view,-

illustrating a further operation of the parts shown in Fig. 5.

Similar characters of reference are employed in all of the hereinabovedescribed views to indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicatesa workbench or other place upon which the novel cork-cutting machine isplaced. The said cork-cutting machine comprises a bed-plate 2 supportedupon suitable legs 3. Arranged upon said bed-plate 2 are a pair ofbearing-elements 4 in which is journaled a shaft 5. Se cured upon saidshaft 5, in a suitable location, is a pulley-wheel 6', to which may beconnected a belt for driving the same, so as to rotate the said shaftThe forward end of said shaft is provided with a chuck-device 7 which isadapted tosupport in operative connection with the said shaft 5, acutting-knife 8, which is of the usual hollow cylindrical form. Securedupon the rear end of said shaft 5 is a grooved collar 9, in the grooveof which is arranged a slipring 10 having oppositely and outwardlyextending studs or lugs 11. Secured to the under side of said bench 1are bearing-members 12 in which is journaled a rock-shaft 13, andconnected with said rock-shaft is a lever-member 14:, the upper end ofwhich is provided with a yoke 15 having its forked ends in engagementwith said studs or lugs 11 of the said slip-ring- 10. Secured to theunder side of said bench 1, in a suitable location, are suitable hangers1G in which is journaled a driving shaft 17. Connected with said drivingshaft 17 is an eccentric 18 from which extends aconnecting-rod 19, thefree end of which is pivotally connected wit-h the forked end 20 of saidlever-member 14 hereinabove mentioned, Connected with said driving-shaft17 is another eccentric 21 from which extends a connecting-rod 22,

and suitably secured to the under side of said bench 1 is a bracket 23upon which is pivotally'mounted a lever-arm 24 to the lower forked end25 of which is pivotally connected the said connecting-rod 22.Connected, in any suitable manner, to the upper end of the saidlever-arm 24 is one end of a coiled spring 26, the opposite end of saidspring being anchored upon a hook-member 27 which is also secured to theunder side of the said bench 1. The said eccentric 21 works inalternation, or in opposite direction, to the movement of said eccentric18, and the lever-arm 24 and said coiled spring 26 act as a balancingdevice to balance the 4 reciprocations of said eccentric 18 whichreciprocates the cork-cutting devices, thus preventing any jarring ordislocation of the mechanism, and providing a smooth, nonvibratingoperation of said cork-cutting machinery. The said bed-plate 2 is formedwith a suitable cork-receiving chute 28 which is located below thecutting-knife 8, above described. The said shaft 5 is hollow, as is alsothe cutting-knife 8, and extending throughsaid shaft 5 is a stationarypushrod 29, the same being suitably secured and 4 supported by means ofa standard-piece 30.

When said shaft 5 has been moved forward to carry the said cork-cuttingknife 8 forward and thereby cutting a cork from the cork-bark presentedin front of the same, the said cutting-knife 8 in cutting said corkreceivesthe same within its tubular interior. When said shaft 5 and saidcuttingknife 8 a are retracted to their normal initial. posii into saidchute 28.

tions, the cork is brought against the free end of said stationarypush-rod 29 which forces the same out of said cutting-knife 8, and theproduced cork will thereupon drop The means for feeding the cork-bark infront of the cutting knife 8, and retaining the same in position duringthe cutting operation comprises the following devices Secured upon saidbed-plate 2 is a frameplate. 2. Said frame-work 31 is provided withoppositely arranged bearingsportions 36 through; which extends adriving-shaft 37, saiddriving-shaft 37 being journaled in suitablebearing-members 38 which are suitably secured upon said bed-plate 2.Said shaft '37 is also provided with a pulley 39 whereby the same may berotated. Secured upon said shaft 37 between the side-members of saidframe-work 31, is feed-roller 40 which is provided with a set-screw 41for locking the same upon said shaft, so that it will rotate therewith.The side-members of the frame-work 31 are provided with rearwardlyext-ending lugs or arms 42, and extending between said sideanembers ofsaid frame-work 31 and above the feed-roller 40 is a supporting-table43, the same being provided with downwardly extending lugs or ears 44which register with said lugs or arms 42 of said frame-work 31, andwhich are secured thereto by means of screws 45, or other suitablefastening means, whereby said supporting-table 43 is maintained in itsoperative position. The said supporting table 43 extends both forwardlyand rearwardly of said frame-work 31, and the same is further providedwith a suitable opening 46 through which may project upwardly the saidfeed-roller 40. The rearward portion of said supporting table 43 isprovided along one of its side-edges with a flange or rib 47, and uponthe side opposite the said rib 47, there is adjustably secured, inconnection with said supporting-table 43, a gage-plate 48, which may besecured in any desired adjusted position by means of a thumb-screw ornut49 arranged in connection therewith. The said supporting table isadapted to support in engagement with said feed-roll 40, a piece ofcork-bark 50 from which it is desired to cut the corks. Slidablyarranged in connection with said framework 31 is a yoke-piece 51 whichis provided with downwardly extending arms 52, in the free ends of whichis support-ed or journaled a shaft 53, the latter being adapted to passthrough elongated slots or openings 54 with which the said side-membersof said frame-work 31 is provided. Secured upon said shaft is anidler-roller 55 which is adapted to rest upon the upper surface of saidcork-bark 50, and the weight of which tends to maintain said cork-barkin its proper engagement with said feed-roll 40, whereby the same ismoved or fed forwardly in front of the reciprocating cutting-knife 8,herein-above described. Adjacent to the said feeding mechanism, justdescribed, and in proper relation thereto, is a cutting-block or anviland an automatic stop-mechanism operating in relation therewith. Thereference-character 56 indicates the said cutting-block or anvil, thesame registering in position with one edge of the forward portion ofsaid supporting table 43, said cutting-block or anvil 56 being supportedin alinement with the said cutting-knife 8, and in such a manner, so asto permit of the adjustment of said cutting-block or anvil with relationto said cutting-knife 8. The means for thus supporting saidcutting-block or anvil comprises a tail-piece or arm 57 which is rigidlysecured to the said cutting-block or anvil in any suitable manner, saidtail-piece or arm 57 being slidably received in the socketed portion 58of a supporting standard 59, which is secured upon said bed-plate 2.Said socketed portion 58 is provided with a setscrew (30, by means ofwhich the said tailpiece or arm 57 may be locked against longitudinalmovement, and thus rigidly main tain said cutting block or anvil in itsadjusted position. The face of said cuttingblock or anvil 56 is providedwith a socket or depression in which is secured a cuttingseat 61 of softmetal, such, for example, as lead, or similar material. The edge of thecutting-knife 8, in the course of the cutting operation fetches upon oragainst this cutting-seat 61, which, being soft, does not in jure thecutting edge of said knife, as will be clearly evident.

The said cutting-block or anvil 56 is provided with a transverse opening(52 in which is slidably arranged a movable stop-member 63 adapted to beprojected beyond the face of said cutting-block or anvil 56 to engagethe cork-bark and hold or retain the same against movement by thefeeding mechanism during the operation of the cork-cutting device. Thesaid stop-member is reciprocated in time, with the movements of thecutting-knife 8, so as to properly operate in conjunction therewith. Themeans for reciprocating said stop-member 63 comprises a tail-piece 6 1which is operatively connected with said stop-member in any suitablemanner, said tail-piece Get being slidably supported by thesocket-portion 65 of a standard 66 which is secured upon said bed-plate2.. The said tail-piece 64 is provided with a plurality of holes orperforations 67, through any one of which may be passed the transversepin 68, to adjust said stop-member 63 with relation to its oper atingmeans, and thereby conform its operation to the adjusted position ofsaid feeding mechanism and said cutting-block or anvil 56, and connectedwith said transverse pin 68 is the link-portion 69 of a reciprocatinglever 70, which is secured upon a rock-shaft 71 journaled in bearings 72 upon the under side of said bed-plate 2. Said bed-plate 2 is providedwith an elongated slot or opening 7 3 which permits the passage andoperation of said reciprocating lever 70. The lower end of saidreciprocating-lever is provided with a forked portion 7 1 which ispivotally connected with the arm 75 of an eccentric 7 6 mounted upon andoperated by said driving shaft 17. Secured to said cut ting-block oranvil 56 and in alinement with said supporting table 13 is a chute -likemember 77 which is adapted to carry off the scrap cork-bark, after thecorks have been cut therefrom.

The operation of my novel construction of cork-cutting machine, thedetails of which have been above described, is as follows: The saidshaft 5 is revolved, so as to revolve said cutting-knife 8 connectedtherewith. A piece of cork-bark 50 is placed upon the supporting table43 and pushed into contactwith the feed-roller 40 and the idler-roller55, the former of which grips it and feeds the same forward in front ofsaid cuttingblock or anvil 56. In the meantime, the said driving-shaft17, operating through the eccentric 7G, oscillates said lever 70 whichpushes forward the said tail-piece G4 and projects beyond the face ofsaid cuttin block or anvil 56 and into the path of said cork-bark 50,the stop-member 63, being thereby held against any forward movement. Inthe meantime, the eccentric 18 operating through its connecting rod 19and the lever-member 14:, moves toward the cutting-block or anvil 56,the rotating shaft 5 and the cutting knife 8 carried thereby, until thelatter cuts its way through said cork-bark 50, thus forming a cork whichis withdrawn from said cork-bark 50 upon the retraction of the saidcutting-knife 8. The eccentric 18 in com iileting its revolutionreverses the movement of said shaft 5 and said cutting-knife 8, which isretracted. Atthe same time, the eccentric 76, in the same manner,oscillates said lever '70 in the opposite direction to retract saidtail-piece at and withdraw said obstructing stop-piece (33 from the pathof said cork-bark 50, which again permits the feed roller 10 to move thesaid cork-bark in a forward direction. The continued revolution of saideccentric 76, operating through the connecting mechanism described,again projects the stoppiece forward, so that the same will enter thehole 7 8, from which the cut cork has been removed (as illustrated moreparticularly in Fig. 6 of the accompanying drawings,) thus again holdingthe corkbark 50 against movement, while the cutting-knife 8 is againmoved into its cutting operation. These operations are continued untilthe cork-bark has been used up, it being understood that the cork-barkpieces are continually caused to follow one another through thefeeding-mechanism by the operation of the machine.

It will be noticed from the above description, and also from aninspection of the accompanying drawings, that the feeding mechanism, theautomatic stop-device, and the said cutting block or anvil may beshifted longitudinally with relation to the bedplate 2, and theseseveral devices may there fore be secured in any desired adjustedposition with relation to the reciprocating cutting-knife 8. The purposeof thus making such parts of the machine adjustable, as to theirposition, is to enable the same to be set up to the proper stroke of thereciprocating cutting knife, and to permit of the sharpening of saidcutting knife, which reduces its length and thereby slightly modifiesits stroke from time to time, as the same is sharpened.

I am fully aware that some changes may be made in the severalarrangements and combinations of the parts of the novel corkcuttingmachine, as well as in the details of the construction of the same,without de parting from the scope of my present invention. Hence, I donot limit my inven tion to the exact arrangements and coinbinations ofthe parts as herein described, and as illustrated in the accompanyingdrawings, nor do I confine myself to the exact details of theconstruction of the said parts.
